摘要

The Ramsey fringes on the ground-state hyperfine transition of ^(199)Hg^(+)(ΔF=1,ΔmF=0)ions trapped in a hyperbolic Paul trap are firstly observed with the method of time-separated oscillatory fields.The full width at half maximum of central Ramsey fringes is about 25 mHz and the corresponding quality factor Q of the line is greater than 10^(12) for the trapped ^(199)Hg^(+)microwave frequency standard.The hyperfine transition frequency shifted by magnetic field is also measured by the high-resolution Ramsey fringes.The final result isΔνhfs=40507347997.3(0.5)Hz,which is corrected to zero magnetic field.
